Title: Infrared ray absorption filter
Inventor: SHIMOMURA TETSUO
IPC: G02B5/22
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To make a filter have absorption in a near-infrared ray region, to improve the light transmissivity in a visible region and to prevent the filter from having the large absorption of a specified wavelength in the visible region by making the transmissivity in the near infrared ray region of a specified wavelength range less than a specified value. SOLUTION: For this infrared-ray absorption filter, the transmissivity in a near infrared-ray region of a wavelength 800 nm-1,100 nm is less than 30%. Since the transmissivity in this area is low, in the case of using it in a plasma display or the like, unrequired infrared rays emitted from the display are absorbed and the malfunction of a remote controller using the infrared rays is prevented. Also, it is desirable that the difference of the maximum value and minimum value of the transmissivity in the visible region of the wavelength 450 nm-650 nm be within 10%. When the transmissivity difference of the wavelength 450 nm-650 nm is within the range, the color tone becomes gray and in the case of placing it on the display front surface, the color tone emitted from the display is expressed without being changed.  Further, it is preferable that the transmissivity of the wavelength 550 nm is more than 50%.

Title: Preamplifier
Inventor: YOSHIKAWA YOSHIKAZU
IPC: H03F3/08
Filed: 1987-05-08
Abstract: PURPOSE:To improve the S/N without deteriorating the frequency response by connecting two sensors converting an input light quantity into an electric quantity so that the change in the detection is opposite to each other, and connecting the one to a base of an amplification transistor(TR) and the other to the emitter while not deteriorating the frequency response. CONSTITUTION:With a change in the input light quantity to sensors 1, 1', a current changes in response to the quantity and the change appears across the resistors 2, 2' as a voltage change and the voltage Vi' at a connecting point between the sensor 1' and the resistor 2' and the voltage at a connecting point between the sensor 1 ' and the resistor 2' are opposite to each other. A signal input Vi' is impressed to a base of a TR 7 via a signal frequency band-pass capacitor 3 and a signal input Vi is impressed to the emitter of the TR 7. Since the two signal inputs Vi, Vi' are opposite to each other, a signal output voltage S1 at the collector of the TR 7 is the sum of two input signals Vi, Vi' multiplied with gains G1, G2 of the TR 7 respectively. Thus, the signal component of the output of the TR is increased thereby improving the S/N.
